Power tool having rotary input control

A power tool comprising:

• a housing;
• an input member coupled to the housing and configured to generate a first signal that corresponds to a detected user input to activate the power tool;
• an output member coupled to the housing and configured to rotate about a longitudinal axis;
• a motor contained in the housing and drivably coupled to the output member to impart rotary motion to the output member;
• a rotational motion sensor arranged in the housing and operable to generate a second signal that corresponds to detected rotational motion of the housing about an axis of the housing;
• and
• a control circuit in the housing:
• (a) that is activated upon receipt of the first signal;
• and, (b) upon or after activation of the control circuit and based upon receipt of the second signal, determines a direction of the rotational motion of the housing about the housing axis, and drives the motor to drive the output member in a direction that corresponds to the rotational motion of the housing.
